<h2>Mishka's speed = 14 km/hr</h2><h2>Current speed = 2 km/hr</h2>

Step-by-step explanation:

Let the speed of rowing be r and speed of current be c.

If he rows with the current, Mishka rows 48 km in 3 hours.

        Relative speed = r + c

        Distance = 48 km

        Time = 3 hours

        48 = 3 x ( r+c)

        r + c = 16 ---------------------------eqn 1

If he rows against the current, it takes 4 hours to travel the same distance.

        Relative speed = r - c

        Distance = 48 km

        Time = 4 hours

        48 = 4 x ( r - c)

        r - c = 12 ---------------------------eqn 2

eqn 1 + eqn 2

        2r = 28

          r = 14 km/hr

Substituting in eqn 1

         14 + c = 16

                c = 2 km/hr

Mishka's speed = 14 km/hr

Current speed = 2 km/hr

You are ordering DVD's from a web site. They charge $14 for each DVD. For any order you must pay an additional $6 for shipping a
valkas [14]

Answer:

y = 16x + 6

Step-by-step explanation:

They charge $14 for each DVD, which mean the slope of the function is 14

You must pay an additional $6 for shipping and handling, which means no matter how many DVD you buy, you have to pay a flat fee for $6  

So our function is:

y = 16x + 6 where:

y is total cost

x is the number of DVD you buy (x>0)
